Problem with Kitodo search plugin

[stweil]

I want to install Kitodo.Presentation's main branch with TYPO3 v12 and cannot get search results from the search plugin.
A similar installation based on the 5.1.x branch with TYPO3 v11 has a working search.

Here are extracts from the Solr request logfile when a single search for "test" is done.

Good search with correct results (branch 5.1.x):

Bad search without any result (main branch):

127.0.0.1 - - [21/Aug./2025:18:15:40 +0000] "GET /solr/admin/cores?wt=json&json.nl=flat&action=STATUS&core=dlfCore1 HTTP/1.0" 200 1117

If I disable search suggestions which were initially enabled for both settings, the main branch throws an exception:

 Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1580585079: No valid parameter passed! | InvalidArgumentException thrown in file /var/customers/webs/weil/viewer/vendor/kitodo/presentation/Classes/Middleware/SearchSuggest.php in line 59. Requested URL: https://digital.ladenburg.world/ 

The results when I access Solr with curl show that both Solr cores (dlfCore0 for 5.1.x, dlfCore1 for main) contain fulltext with the word "test":

@beatrycze-volk, @sebastian-meyer, is this a know or unknown bug of the latest main branch? Or does the search plugin work for you?

[sebastian-meyer]

Summoning @frank-ulrich-weber. He did a major rework of the Solr integration in #454 (and also made Kitodo.Presentation use the proper Solr suggest endpoint for auto-completion in #1289).
